I recently released a horror visual novel, I wouldn't say it has anything within it like a traditional jumpscare. 
Vacation Terminal is a short 2D Psychological thriller, horror and survival based visual novel with evading based puzzle elements. Following the story of two strangers, Gavriil and Yeva, who suddenly find themselves stranded in the snowy wilderness after a brutal train crash. To survive, they must put trust each in each other and lean on the hope for eventual rescue. 
Gavriil and Yeva, two strangers who happened to meet by chance, both travelling together, on the same train, in the same cabin, but really with not much to talk about. But when their train derails in the middle of nowhere, they're suddenly forced to work together. Gavriil wakes up alone in a cold, pitch-black cave—his leg missing, and Yeva claiming she saved his life. There’s no sign of rescue. No way to call for help ... This was supposed to be just a short vacation. - 9 k words - 1 hour play time - 3 endings total
This is the first game I have ever developed and written, so the mechanics, and storytelling might feel a little off, but I'm still pretty happy with the fact I was able to finish this with the help of many wonderful people, as listed above, please check them all out!
